Motion in Geometry In a rotation every point of a figure moves around a given point known as the Center of rotation Translation: Every Point of a figure moves in a straight line, and all points move the same Reflection- Every point is flipped across a line rotation: transformation in which every point of the preimage is moved by the same angle through a circle centered at a give Fixed point known as the center of rotation


Translation: Every point in a figure moves in a straight line and all points move the same distance and in the same direction.
the paths of the points are parallel.

Rotations: Every point in a figure moves around a given point known as The center of rotation. ALL points move the same measure angle.

Reflection: A line plays the role of a mirror and every point in a geometric figure is flipped across the line!

Rigid Transformations: Transformations that do not change the size or shape of a figure.
perimage and image refer to a shape that undergoes a motion or transformation.
Vertical Angles: The non - adjacent angles formed by intersecting lines.(sometimes called opposite angles).
